Figure 1: DC power sharing connections with multiple non-opto
isolated boosters
Notes: Current Protection Devices
(CPDs) on positive leads should
match each boosters current rating.
Only connect DC power leads to
Pins 7 and 4 with polarity as shown
for safe operation. DC power leads
should be adequately sized for load
and fault currents.
All non-opto boosters should be
connected to the general return via
pin 4.
Power supply sharing is only sup-
ported by non-opto boosters. Opto
boosters must each be powered by a
separate supply.
Other connections omitted for clar-
ity. Ensure connections are correct
and reliable.
